Cool Newsflare archive footage from Prague of eggs with animated, moving patterns on them, designed in a scientific way and drawn by a robot.

The footage, filmed just before Easter in March 2016, shows different patterns "generated in software called MATLAB, using mathematical equations similar to ones describing Spirograph and Phyllotaxis," according to the filmer.

"The patterns are calculated in such a way that when rotated under a stroboscopic light of suitable frequency or when recorded by a camera, they start to animate," he continued.

Easter eggs with animated patterns designed in scientific way and drawn by a robot. Various patterns are generated in software called MATLAB using mathematical equations similar to ones describing Spirograph (or harmonograph) and Phyllotaxis. The patterns are calculated in such a way that when rotated under a stroboscopic light of suitable frequency or when recorded by a camera, they start to animate. It is kind of zoetrope---early device for animation. Eggs were painted using EggBot (designed by Bruce Shapiro as open hardware and available as a kit from Evil Mad Scientist). To draw on eggs, standard permanent markers and an electro kistka with bee wax followed by dying were used. Eggs are rotated at a constant speed, special for each pattern, by an electric motor. No computer graphics tricks are used in the video. The patterns were designed by PhD student Jiri Zemanek from Czech Technical University in Prague, Faculty of Electrical Engineering, Department of Control Engineering (http://aa4cc.dce.fel.cvut.cz/). He is also author of the video.
